) -> Result<QueryPool, QueryPoolCreationError>

Builds a new query pool.

pub fn ty(&self) -> QueryType

Returns the QueryType that this query pool was created with.

pub fn num_slots(&self) -> u32

Returns the number of query slots of this query pool.

pub fn query(&self, index: u32) -> Option<Query<'_>>

Returns a reference to a single query slot, or None if the index is out of range.

pub fn queries_range(&self, range: Range<u32>) -> Option<QueriesRange<'_>>

Returns a reference to a range of queries, or None if out of range.

Panic

Panics if the range is empty.
